Variation of leaf and wood decomposition with elevation in the Peruvian Andes

How sensitive are decomposition processes to temperature?
This project exploits the gradient in temperature along the slopes of the Andes to conduct a large-scale translocation experiment of wood and leaf litter, to understand the sensitivity of decomposition to temperature, and the interspecific variation in decay rates.

This work is the DPhil project of Norma Salinas, who is a lecturer at the Universidad San Antonio Abad in Cusco and completing her DPhil at Oxford University.

Congratulations to the GEM team (Chris, Yadvinder & Liana) who co-authored a paper in Nature this week (cover story):

"The paper answers a long-standing question about the net carbon balance of the Amazon forest. It uses aircraft flights throughout the year at four different locations to measure the change in carbon dioxide concentration if air as it passes over the Amazon Basin. The study shows that in wet years and wet seasons the Amazon is a net sink (i.e. absorbs carbon) from the atmosphere, but in dry years and dry seasons it is carbon neutral or a source of carbon. Our main contribution in Oxford was to provide insight from our RAINFOR-GEM intensive monitoring plots across Amazonia, which suggest that the loss of the carbon sink was caused by a reduction in photosynthesis."
